AUTOMATIC WEIGHING- APPARATUS.

Specification of Letters Patent.

Patented Nov. 16, 1915..

Application filed June 7, 1905. Serial No. 264,053.

To all whom it may concern Be it known that I, HENRY RICHARDSON, a subject of the King of Great Britain, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Automatic Weighing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an automatic and continuously Wei hing and registering device, the object oing to'provide a device which is simple in construction and by which granular, powdered and liquid materials may be automatically and continuously weighed and registered.

In my invention I utilize the force of gravity of a falling body as motive power, actuating an ordinary conveying band, onto and over which the materials are delivered,

and by the movement of which band, in its relation to the weighing device andcounta modification of the conveyer as adapted to weigh liquids. Fig. 5 is a further modification showing an apparatus wherein the scale beams are dispensed with, the counter or cyclometer registering the amount of material carried by the conveyer.

Like numerals refer to like parts throughout the several figures.

1 represents the feed chute which delivers the material to be weighed into the hopper 2, consisting of an upper part as 3 and a lower part as 4, said upper part 3 consisting of four walls, two of which, 5 and 6, are vertical, the other two, 7 and 8, being inclined. This formation permits of a more regular feeding of certain materials. The lower portion of the hopper forms the discharge spout, and is inclosed on three sides by the walls 10, 11 and 12, the inclination of these sides being arran ed to suit the angle of repose of the material being weighed.

The walls 10, 11, and 12 are shown as statlonary, but this is not essential. The bellshaped opening 14, extends toward the conveyer, 13, and by the omission of one side permits the conveyer 13 to take away the material in the direction indicated by the The correct line of the conveyer insures suflicient friction between the conveyer and material to utilize the weight of the latter as motive power in driving the former. This principle is well known, being the principleempl'oyed in-a tread mill where the weight of a man or animal acting upon a series of steps, or an endless band, furnishes driving power.

The various parts of the mechanism are supported by horses 18 and 19', at the to of which are rigidly secured four standar s 20, 21, 22 and 23, having recessed tops form-.

ing the fulcrums for the scale beams, 24, 25, 26. and 27; the shorter arm 28, of which beams carry the supports of the conveyerframe, 29, and the longer arms are connected to the pendulum weight 35, by links 33. The supports 42, 43, 44 and 45 take the hear.- ing of the conveyer on the knife'edges of the weighing apparatus. The drum 16'is made adjustable b means of a screw 53, and this provides or any required inclination in the conveyer.

In order to register the weight of thematerial passing over the band, the friction roller 56 coupled to the cyclometer 54 by means of the friction roller 58, is mounted upon the arm 59, which is rigidly attached to the pendulum weight 35, which extends to the drum shafts, to which latter is attached the disk, 55, and upon the face of this the friction roller 56 revolves.

It will thus be seen that the registering of the cyclometer increases as it moves from the center to the periphery of the disk 55, and this movement is in relation to the weight of the material falling on to the topof the conveyer. Thus the varying weight of material fed upon the conveyer 13, produces-a corresponding deflection on the pendulum and registers the weight of the mate.- rial no matter how the supply of the latter from the chute fluctuates,

When the supply to the belt ceases and the conveying belt is empty, the position of the friction roller will be in the center of the disk, at which position it ceases to revolve.

It will be obvious that the construction of a device to accomplish the aforementioned results, has many points of advantage and modifications not specially mentioned above, and details in the construction may be changed without departing from the spirit of my invention, as claimed. I, therefore, wish to avail myself of such modifications and equivalents as fall properly within the spirit of my invention.

In Fig. 4 I have shown a modification of the device wherein the conveyer is provided with external liquid-receiving cups, and in Fig. 5 a conveyer which operates without the use of a scale beam.

Having thus described my what I claim as new therein and secure by Letters Patent is:

1. In an apparatus of the character herein specified, the combination of a conveyer, means for uninterruptedly supplying material to said conveyer, the latter being at an inclination to be driven solely by the gravitation of the material thereon, and a registering apparatus controlled by the weight of the material traveling with the conveyer and having means foroperating it at a rate determined also by the rate of movement of the conveyer.

2. In an apparatus of the character herein specified, the combination with a band or conveyer mounted on an incline and adapted to be driven by the gravity of the material being weighed, of a supply hopper mounted above the conveyer, and a registering apparatus having means for actuating it by said conveyer and at a rate determined by. the rate of movement of the conveyer and also controlled by the weight of material traveling with the conveyer.-

3. In a device of the character herein specified, a receiving hopper provided with a discharge adapted to regulate the flow of material therefrom, the upper portion of the hopper having two vertical walls and two walls placed at an angle, and the lower portion of the hopper being inclosed by three Walls placed at an angle and suited to the angle of reposeof the material to be weighed, the front of the lower part ofthe hopper being open forming a discharge, substantially as shown and described.

4. In an apparatus of the character herein specified, the combination of a conveyer arranged at an inclination and operative by the weight of material thereon, weighing mechanism having a drum supported thereby over which the conveyer passes, a frictlon wheel rotativewith said drum, a registering device, and means for operating said invention, desire to friction wheel rotative with said drum,-

weighing mechanism yieldingly supporting said drum, a registering device, and means for operating said registering device, including a friction wheel cooperative with said weighing mechanism and movable in contact with the side face of the other wheel.

.6. In an apparatus of the character herein specified, the combination of a flexible traveling conveyer adapted to support a moving stream of material, means for uninterruptedly supplying material'tosaid conveyer to impart a traveling movement thereto, and a registering device cooperative with the conveyer and operable at a rate determined by the weight of. the material and said traveling movement of the conveyer.

In an apparatus of the character herein specified, the combination of a conveyer arranged at an inclination and adapted for traveling movement, means for uninterruptedly supplying material to the upper end thereof to operate the same, and a registering device cooperative with the conveyer and operable by the weight of said material to register said traveling movement.
